Description

The Holy Well of St Stephen is a Grade II listed site located in Launceston. It consists of 18th and 19th century structures built on an ancient site. The well-heads are made of slatestone rubble, with dressed greenstone and granite. The presumed older structure is integrated into a hedge, featuring a large sump that is covered with slate slabs, one of which is broken and another supported by a stone prop. Another structure, believed to be from the 19th century, has an inverted doorway and a front gable end with kneelers. It also features a round-arched doorway with a keyblock and an inner order made of re-used 17th century chamfered granite. Inside, there is a segmental-arched stone vault that supports the stone roof.
